Description

Technical Field

[0001] This invention relates to the field of threaded installation technology, and in particular to an orientable threaded installation structure and its installation method. Background Technology

[0002] Currently used threaded installation structures lack directional functionality due to the random distribution of the starting and ending positions of the threads. For example, Phillips head screws cannot guarantee that the Phillips head will always be vertical or horizontal after installation. Furthermore, commonly used directional structures use a stop for orientation and then require thread locking from inside the equipment. Disassembly and assembly of threaded structures require disassembling the equipment.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: how to provide a threaded mounting structure that can be installed and disassembled outside the equipment and whose final installation direction is controllable.

[0005] The present invention adopts the following technical solution:

[0006] In a first aspect, an orientable threaded mounting structure is provided, comprising: a fixing component 1 and a movable part 2, wherein the fixing component 1 is disposed on the device and the movable part 2 is mounted on the fixing component 1;

[0009] The movable part 2 is used to connect with the nut 11. The movable part 2 is rotated continuously in a preset locking direction so that the nut 11 slides in the fixed seat 10 until the boss 20 is engaged with the bayonet 100.

[0010] When the boss 20 is fully engaged with the bayonet 100, the elastic body 12 is used to reset the nut 11, and the nut 11 is used to pull the movable part 2 to lock the movable part 2.

[0017] The nut 11 has a protrusion 111 at the other end. One end of the elastic body 12 abuts against the limiting block 104, and the other end of the elastic body 12 is connected to the nut 11. The protrusion 111 is used to prevent the elastic body 12 from slipping out.

[0018] Preferably, the boss 20 includes a first limiting surface 200 and a second limiting surface 201, the first limiting surface 200 and the second limiting surface 201 being inclined surfaces or straight surfaces, and the shape of the bayonet 100 matching the first limiting surface 200 and the second limiting surface 201.

[0026] When the angle of the first limiting surface 200 is less than the angle of the second limiting surface 201, the locking torque of the movable part 2 is greater than the unlocking torque of the movable part 2.

[0027] Preferably, both the first limiting surface 200 and the second limiting surface 201 are straight surfaces, including:

[0028] When the movable part 2 is locked or unlocked, the boss 20 enters the slot 100 of the fixed seat 10 and pulls the movable part 2 outward along the axis of the movable part 2 until the boss 20 disengages from the slot 100 on the fixed seat 10, and then the movable part 2 is locked or unlocked.

[0029] Secondly, a method for installing an orientable threaded mounting structure is provided, the method comprising:

[0030] Connect the movable part 2 to the nut 11, and rotate the movable part 2 continuously in the preset locking direction so that the nut 11 slides in the fixed seat 10 until the boss 20 is engaged with the bayonet 100;

[0031] When the boss 20 is fully inserted into the bayonet 100, the elastic body 12 resets the nut 11, and the nut 11 pulls the movable part 2 to lock the movable part 2.

Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0056] In this invention, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0057] In this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0058] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] Example 1:

[0060] In existing technologies, commonly used threaded installation structures such as cross-slot screws and threaded bolts cannot guarantee that the cross-slot will always be vertical or horizontal after installation because the starting and ending positions of the threads are randomly distributed. This may make it difficult to control the direction during installation or disassembly, requiring adjustments based on the actual situation. At the same time, for threaded connections using directional structures, disassembly may require thread locking from the inside of the equipment. This means that the equipment may need to be disassembled before disassembly can be performed, increasing the complexity and workload of disassembly.

[0061] To address the problems existing in the prior art, Embodiment 1 of the present invention provides an oriented threaded mounting structure, such as... Figure 1 As shown, the device includes a fixed component 1 and a movable part 2. The fixed component 1 is disposed on the device, and the movable part 2 is mounted on the fixed component 1. The fixed component 1 can be fixed inside the device, or, under certain specific requirements, it can be fixed outside the device, depending on the actual situation. The movable part 2 can be selected according to actual usage needs. The movable part 2 matches the fixed component 1, allowing for installation and removal from the outside of the device. After installation, except for the portion installed inside the fixed component 1, the rest of the movable part 2 is outside the device, facilitating external use. The movable part 2 can be an L-shaped screw, with the external L-shaped bend used for holding items; its specific structure will be described below.

[0062] In a preferred embodiment, refer to Figure 2 The fixing component 1 includes a fixing base 10, a nut 11, and an elastic body 12. The nut 11 and the elastic body 12 are disposed in the fixing base 10. One end of the fixing base 10 is provided with a bayonet 100, and the movable part 2 is provided with a boss 20. The bayonet 100 matches the boss 20 and is used to control the installation direction of the movable part 2.

[0063] The fixing base 10 is fixed inside the device. This fixing includes, but is not limited to, using an adhesive material to fix the bottom of the fixing base 10 inside the device, and using screws to fix the bottom of the fixing base 10 inside the device. The nut 11 and the elastic body 12 are disposed within the fixing base 10. The elastic body 12 can be a spring; in other embodiments, the elastic body 12 can be replaced with other elastic devices, which will not be further described in this embodiment.

[0064] One end of the fixed base 10 is provided with a latch 100, while the movable part 2 is provided with a protrusion 20. The latch 100 and the protrusion 20 are matched. The shape of the latch 100 can be the same as the shape of the protrusion 20, and the volume of the protrusion 20 is slightly smaller than the volume of the latch 100 to facilitate the protrusion 20 entering the latch 100. The depth of the latch 100 is the height of the protrusion 20. The shape and size of the latch 100 and the protrusion 20 can be set according to actual needs, and are not specifically limited in this embodiment. When the movable part 2 is installed on the fixed component 1, the latch 100 will be correctly aligned with the protrusion 20. The installation direction of the movable part 2 can be controlled by setting the direction of the latch 100.

[0065] The installation method of the nut 11, the elastomer 12 and the fixing seat 10 will be described below.

[0066] In a preferred embodiment, the movable part 2 is used to connect with the nut 11. The movable part 2 is rotated continuously in a preset locking direction so that the nut 11 slides in the fixed seat 10 until the boss 20 engages with the bayonet 100. When the boss 20 is fully engaged in the bayonet 100, the elastic body 12 is used to reset the nut 11, and the nut 11 is used to pull the movable part 2 to lock the movable part 2.

[0067] Among them, such as Figure 3 As shown, in the pre-assembled state, the nut 11, elastic body 12, and fixing seat 10 are in a compressed state, with the elastic body 12 exerting a rearward preload on the nut 11, so that the nut 11 is positioned at the rear end of the fixing seat 10 in the normal state. The preset locking direction is related to the thread distribution inside the nut 11, and can be either clockwise or counterclockwise. In this embodiment, a clockwise direction is used as an example. By locking the movable part 2, the protrusion 20 on the movable part 2 continuously approaches the bayonet 100 until the protrusion 20 contacts the front surface of the fixed seat 10. At this time, if the movable part 2 is rotated, the movable part 2 will drive the nut 11 to move towards the front surface of the fixed seat 10, and the nut 11 will compress the elastic body 12. When the protrusion 20 enters the bayonet 100, the nut 11 will move backward under the action of the elastic body 12, and at the same time drive the movable part 2 to lock until the protrusion 20 is completely entered into the bayonet 100. At this time, the movable part 2 can no longer be rotated, and the locking of the threaded installation structure is completed.

[0068] Compared with the prior art, the beneficial effects of the present invention are as follows: On the one hand, the present invention installs the fixing component on the device and the movable part on the fixing component, and the movable part is located outside the device after installation, thus realizing the installation and disassembly of the threaded mounting structure without disassembling the device; on the other hand, by setting the bayonet and the boss to match, the installation direction of the movable part can be controlled by setting the direction of the bayonet, and the movable part can be stabilized in the required direction.

[0069] The specific structure of the threaded mounting structure will be described below.

[0070] In a preferred embodiment, such as Figure 4 As shown, the movable part 2 includes a screw 21, on which a first thread 22 is provided, and a boss 20 is provided at the tail of the screw 21; the screw 21 is mounted on the nut 11 through the first thread 22.

[0071] In this embodiment, the movable part 2 can be an L-shaped movable part. A screw 21 is provided at the front end of the movable part 2. The first thread 22 on the screw 21 matches the thread in the nut 11. The length of the first thread 22 can include the entire screw 21, or it can be a section of the first thread 22 provided only at the front of the screw 21. This section of the first thread 22 matches the thread on the nut 11.

[0072] The length of the screw 21 is set according to the length of the fixed base 10 and actual needs. The boss 20 is set at the tail of the screw 21. The bent part of the movable part 2 can be set according to actual needs, and can be used as a direction indicator of the screw 21 or for other external uses.

[0073] In order to house the nut 11 in the fixed base 10 and to facilitate the sliding of the nut 11, in a preferred embodiment, such as Figure 5 As shown, the fixing base 10 further includes a sliding groove 101 and a through hole 102, the sliding groove 101 communicating with the through hole 102; the nut 11 is slidably disposed on the sliding groove 101, the inner surface of the through hole 102, the inner surface of the sliding groove 101, and the outer surface of the nut 11 all match, so that the nut 11 can slide in the sliding groove 101 and the through hole 102; as Figure 6 As shown, the nut 11 is provided with a second thread 110, which matches the first thread 22, and the screw 21 is connected to the nut 11 through the through hole 102.

[0074] In a preferred embodiment, to facilitate the sliding of the nut 11 in the sliding groove 101, corresponding sliding components can be provided on the sliding groove 101 and the nut 11. For example, a sliding strip can be provided in the sliding groove 101, and a groove matching the sliding strip can be provided on the outer surface of the nut 11. Alternatively, a groove can be provided in the sliding groove 101, and a sliding strip matching the groove can be provided on the outer surface of the nut 11. Specific implementation details are not described in detail in this embodiment.

[0075] In other embodiments, the bottom of the sliding groove 101 can be flat. In order to reduce the friction of the nut 11 sliding in the sliding groove 101, the bottom of the sliding groove 101 can also be hollow and used in conjunction with the above-mentioned sliding component. The specific implementation method will not be described in detail in this embodiment.

[0076] The nut 11 can be square, and the sliding groove 101 can be flat. In other embodiments, only one surface of the nut 11 needs to be flat to prevent it from flipping over, and this flat surface can be used as the contact surface between the nut 11 and the sliding groove 101. The other surfaces can be of any shape. The sliding groove 101 is used for the sliding of the nut 11. (Refer to...) Figure 5 and Figure 7 One end of the sliding groove 101 is provided with a limiting platform 103, and one end of the nut 11 abuts against the limiting platform 103 to limit the sliding range of the nut 11.

[0077] Reference Figure 3 , Figure 5 and Figure 6 A limiting block (104) is provided between the sliding groove (101) bayonet (100) and the through hole (102), and the elastic body (12) is disposed in the sliding groove (101) through hole (102); the other end of the nut (11) is provided with a protrusion (111), one end of the elastic body (12) abuts against the limiting block (104), and the other end of the elastic body (12) is connected to the nut (11). The protrusion (111) is used to prevent the elastic body (12) from sliding out.

[0078] In the initial state, the elastic body 12 is disposed in the sliding groove 101. One end of the elastic body 12 abuts against the limiting block 104, and the other end of the elastic body 12 abuts against the nut 11. The nut 11 has protrusions 111 to prevent the elastic body 12 from slipping. For example, protrusions 111 can be provided at the four corners of the nut 11 to limit the elastic body 12 around its perimeter. When the elastic body 12 is in a compressed state, it exerts a backward preload on the nut 11. The limiting platform 103 is used to balance the preload exerted by the elastic body 12 on the nut 11. In other embodiments, the limiting platform 103 can also be configured to be closed, and the nut 11 can be blocked by a square block structure to balance the preload exerted by the elastic body 12 on the nut 11. However, this solution requires an opening in the square block structure for the tail of the screw 21 to pass through. The specific implementation method is not described further in this embodiment.

[0079] To facilitate setting the locking and unlocking force of the threaded mounting structure according to actual needs, in a preferred embodiment, such as... Figures 8-10 The boss 20 includes a first limiting surface 200 and a second limiting surface 201. The first limiting surface 200 and the second limiting surface 201 are inclined surfaces or straight surfaces. The shape of the bayonet 100 matches the first limiting surface 200 and the second limiting surface 201.

[0080] Wherein, after the boss 20 contacts the front surface of the fixed base 10 as the movable part 2 rotates, in order to facilitate the rotation of the movable part 2, the two surfaces of the boss 20 are set as inclined surfaces or straight surfaces, which is more conducive to the rotation of the movable part 2. In actual use, there may be different requirements for locking and unlocking forces. Therefore, according to the actual locking force and unlocking force, the first limiting surface 200 and the second limiting surface 201 can be set in the following ways: the first limiting surface 200 and the second limiting surface 201 being inclined surfaces or straight surfaces includes: both the first limiting surface 200 and the second limiting surface 201 are inclined surfaces; or both the first limiting surface 200 and the second limiting surface 201 are straight surfaces; or the first limiting surface 200 is an inclined surface and the second limiting surface 201 is a straight surface; or the first limiting surface 200 is a straight surface and the second limiting surface 201 is an inclined surface.

[0081] It is worth noting that regardless of whether the first limiting surface 200 and the second limiting surface 201 are straight or inclined, the mating surfaces of the latch 100 that are matched with the first limiting surface 200 and the second limiting surface 201 are all aligned. In this embodiment, there are two protrusions 20, arranged symmetrically at the top and bottom. Therefore, the latch 100 also has two corresponding portions for locking the protrusions 20. In other embodiments, multiple protrusions 20 can be provided to ensure that the first limiting surface 200 and the second limiting surface 201 on the protrusions 20 are aligned, which can make locking or unlocking the movable part 2 easier. This will not be elaborated further in this embodiment.

[0082] Among them, such as Figure 8 The diagram shows the locked state of the movable part 2 and the fixed component 1. When the first limiting surface 200 is a straight surface and the second limiting surface 201 is an inclined surface, assuming the clockwise direction is the locking direction, the locking torque of the device is less than the unlocking torque. To unlock, the movable part 2 must first be pulled outwards along its axial direction until the protrusion 20 disengages from the latch 100 on the fixed base 10, and then the movable part 2 is unlocked. When the first limiting surface 200 is an inclined surface and the second limiting surface 201 is a straight surface (not shown in the diagram), assuming the clockwise direction is the locking direction, the locking torque of the device is greater than the unlocking torque. To lock, when a portion of the protrusion 20 enters the latch 100, the movable part 2 must first be pulled outwards along its axial direction until the protrusion 20 disengages from the latch 100 on the fixed base 10, and then the movable part 2 is locked.

[0083] Among them, such as Figure 9 As shown, when the angle of the first limiting surface 200 is greater than the angle of the second limiting surface 201, the locking torque of the movable part 2 is less than the unlocking torque of the movable part 2; when the angle of the first limiting surface 200 is less than the angle of the second limiting surface 201, the locking torque of the movable part 2 is greater than the unlocking torque of the movable part 2.

[0084] Both the first limiting surface 200 and the second limiting surface 201 are inclined surfaces, and their angles affect the locking and unlocking torques of the movable part 2. When the angle of the first limiting surface 200 is greater than the angle of the second limiting surface 201, the locking torque of the movable part 2 is less than the unlocking torque. In this state, unlocking the movable part 2 requires more force, and its locking effect is better. When the angle of the first limiting surface 200 is less than the angle of the second limiting surface 201, the locking torque of the movable part 2 is greater than the unlocking torque. In this case, locking the movable part 2 requires more force. This design may be used to ensure that the device remains stable under specific operating conditions or to provide sufficient force when the device state needs to be changed.

[0085] like Figure 10 As shown, both the first limiting surface 200 and the second limiting surface 201 are straight surfaces. When the movable part 2 is locked or unlocked, after the boss 20 enters the slot 100 of the fixed seat 10, the movable part 2 is pulled outward along the axis of the movable part 2 until the boss 20 disengages from the slot 100 on the fixed seat 10, and then the movable part 2 is locked or unlocked.

[0086] When both the first limiting surface 200 and the second limiting surface 201 are straight surfaces, as the movable part 2 rotates, the boss 20 gradually approaches the bayonet 100. When the boss 20 partially enters the bayonet 100, because the second limiting surface 201 is straight, if the movable part 2 continues to rotate, the boss 20 will get stuck in the bayonet 100 and cannot continue to rotate. At this time, it is necessary to first pull the movable part 2 outward along its axial direction, while simultaneously driving the nut 11 to compress the elastic body 12, and then continue to rotate the movable part 2. When the boss 20 re-enters the bayonet 100, the above operation is repeated until the boss 20 is completely inside the bayonet 100, completing the locking of the movable part 2. When unlocking is required, pull the movable part 2 along its axial direction and rotate it in the opposite direction of the locking direction until it is completely unlocked.

[0087] Example 2:

[0088] In Example 1, a directional threaded mounting structure was proposed. In this example, its mounting method will be further described, such as... Figure 1 , Figure 2 and Figure 11 As shown, the installation method includes:

[0089] Step 101: Connect the movable part 2 to the nut 11, and rotate the movable part 2 continuously in the preset locking direction so that the nut 11 slides in the fixed seat 10 until the boss 20 is engaged with the bayonet 100.

[0090] In conjunction with the aforementioned embodiment 1, such as Figure 12As shown, the screw 21 is passed through the through hole 102 on the fixed base 10 and contacts the nut 11; the screw 21 is rotated in the tightening direction, and the screw 21 engages with the thread of the nut 11. Due to the preload of the elastic body 12, the nut 11 will adhere to the rear end of the sliding groove 101 on the fixed base 10 and abut against the limiting platform 103. As the first thread 22 and the second thread 110 come into contact, the screw 21 slowly screws into the nut 11, and the distance between the boss 20 on the screw 21 and the fixed base 10 gradually decreases. In conjunction with the aforementioned embodiment 1, as... Figure 13 As shown, until it contacts the front surface of the fixed seat 10, the nut 11 remains positioned behind the sliding groove 101 and abuts against the limiting platform 103 due to the preload of the elastic body 12. At this time, the angle α between the tail of the screw 21 and the vertically upward direction is denoted as a0, which is the angle from the tail of the screw 21 to the vertical direction along the tightening direction of the first thread 22, in degrees, and can be any angle.

[0091] Step 102: When the boss 20 is fully inserted into the bayonet 100, the elastic body 12 resets the nut 11, and the nut 11 pulls the movable part 2 to lock the movable part 2.

[0092] When the screw 21 continues to be rotated in the tightening direction, the boss 20 on the screw 21 will be in contact with the front surface of the fixed seat 10 and will be supported by the fixed seat 10. The screw 21 cannot move axially to the rear side of the fixed seat 10. As a result, the screw 21 will pull the nut 11, causing the nut 11 to move axially towards the front end of the fixed seat 10 in the sliding groove 101 and the through hole 102.

[0093] Continue rotating the screw 21 in the tightening direction. The angle α between the tail of the screw 21 and the vertically upward direction gradually decreases. When α decreases to 0, the boss 20 aligns with the slot 100 on the fixed seat 10. The nut 11 moves forward axially a distance L1 = a0 / 360*p, where p is the thread pitch. At this point, the screw 21 is not in contact with the fixed seat 10, the supporting force of the fixed seat 10 on the screw 21 disappears, and the nut 11 is subjected to the elastic force of the elastic body 12. The nut 11 will drive the screw 21 to move backward until it contacts the limiting platform 103. The distance it moves is L1, which is also the depth to which the boss 20 on the screw 21 enters the slot 100.

[0094] In conjunction with the aforementioned embodiment 1, such as Figure 14As shown, based on the shapes of the first limiting surface 200 and the second limiting surface 201 on the boss 20 described in Embodiment 1, different locking methods are selected, which will not be repeated in this embodiment. If the screw 21 is rotated further, causing the boss 20 to disengage from the bayonet 100, the boss 20 will then contact the front surface of the fixing seat 10. The screw 21 will drive the nut 11 to move axially toward the front surface of the fixing seat 10. When rotated to a = 0, the distance L2 = a0 / 360 + 1*p that the nut 11 moves forward axially is reached. At this point, the screw 21 is no longer in contact with the fixing seat 10, and the supporting force of the fixing seat 10 on the screw 21 disappears. The nut 11 is subjected to the elastic force of the elastic body 12, and the nut 11 will drive the screw 21 to move backward until it contacts the limiting platform 103. The distance of movement is L2, which is also the depth to which the boss 20 enters the bayonet 100. By repeating this process, we can obtain:

[0095] When a = 0 for the first time, L1 = a0 / 360*p;

[0096] When a = 0 for the second time, L2 = (a0 / 360 + 1) * p;

[0097] When a = 0 for the third time, L3 = (a0 / 360 + 2) * p;

[0098] When a = 0 for the Nth time, Ln = (a0 / 360 + n - 1) * p.

[0099] In conjunction with the aforementioned embodiment 1, such as Figure 15 As shown, when Ln is greater than the height of the boss 20, the boss 20 is fully inserted into the bayonet 100, which indicates that the installation is complete.

[0100] The specific structure of the directional threaded mounting structure is described in Example 1 and will not be repeated in this example.

[0101] Example 3:

[0102] In Example 1, an orientable threaded mounting structure was proposed. In this example, an example of the use of the threaded mounting structure will be presented to further illustrate the structure.

[0103] like Figure 16 As shown, a chassis-type product is provided, with two fiber optic brackets on the front panel to support and fix the optical fibers. The tail of the brackets is required to be vertically upward for supporting and fixing the optical fibers or cables. Since the fiber optic brackets are located outside the chassis, the overall size of the chassis increases, leading to higher packaging and transportation costs and hindering equipment installation. By using a threaded mounting structure, the fixing component 1 is housed inside the chassis, and the fiber optic brackets are designed as detachable movable parts 2. Figure 17As shown, after the equipment inside the chassis and the fixed component 1 are installed, the movable part 2 is then installed. The vertical structure at the tail of the movable part 2 can be used to support and fix the optical fiber or cable outside the chassis, thereby reducing packaging and transportation costs.

[0104] The specific structure of the threaded mounting structure is described in Example 1, and the installation method of the threaded mounting structure is described in Example 2. These details will not be repeated in this example.
